svn commit: r1484747 - in /mahout/trunk: CHANGELOG core/src/main/java/org/apache/mahout/clustering/streaming/cluster/StreamingKMeans.java

Author: dfilimon
Date: Tue May 21 10:52:25 2013
New Revision: 1484747

URL: http://svn.apache.org/r1484747
Log:
MAHOUT-1223: Fixed point being skipped in StreamingKMeans when iterating through centroids from a reducer

When calling StreamingKMeans in the reducer (to collapse the number of clusters
to they can fit into memory), the clustering is done on the Hadoop reducer
iterable.
Currently, the first Centroid is added directly as a special case and then is
skipped when iterating through the main loop.
However, Hadoop reducer iterables cannot be rewound therefore causing SKM to
skip one point.

Log:
MAHOUT-1222: Fix total weight in FastProjectionSearch

Sometimes when removing a Vector that's in pendingAdditions, the wrong Vector
gets removed.
This happens because the closest Vector is removed rather than the one that's
equal to it.

CPU, Disk and Memory requirements are based on the many choices made in implementing your application with
Mahout (document size, number of documents, and number of hits retrieved to name a few.)

Several of the Mahout algorithms are implemented to work on Hadoop clusters. If not advertised
differently, those implementations work with Hadoop 0.20.0 or greater.

Log:
MAHOUT-1219: LSHSearcher not always faster than BruteSearcher

The existing "benchmark" is not conclusive enough as it doesn't take into
account the adaptive nature of the JVM, doesn't run the test multiple times and
should be replaced with something more thorough.
Removing LSHSearcher from the tests for now.

This fixes FastProjectionSearch's searchFirst() which was not also searching
through pendingAdditions. I think I replicated the bug in the new testRemove()
in SearchSanityTest that now passes.
